After receiving a doctorate in Computer Science from Cornell, I taught at Harvard and the State University of New York at Albany before becoming a member of the Department of Computer Science at the University of Kentucky. Sabbatical leaves were spent at Yale, the University of California at Berkeley, and the Mayagüez Campus of the University of Puerto Rico. In addition, a summer was spent at Fond du Lac Tribal College.

During the early 1990's, while at Kentucky, I was on detail to the National Science Foundation (NSF) in Washington, DC. For the first year and a half I served as program director for the Programming Languages and Compilers and the Operating Systems and Systems Software programs in the Division of Computer and Computation Research in the Computer and Information Science and Engineering Directorate.

At this point I joined NSF's Office of Cross Disciplinary Activities and spent a year as program director for the Research Instrumentation, Academic Research Infrastructure, NSF Young Investigators, and Research Experiences for Undergraduates (Sites) programs. In addition, and of particular interest during this period was my involvement with minority institutions as program director for the Institutional Infrastructure for Minority Institutions program as well as special projects involving minority education and research.

For the next five years, (after returning to Kentucky), I served on the Advisory Committee for the Fond du Lac Tribal College in Cloquet, Minnesota and the Advisory Committee for the new PhD program (in computer science and engineering) at the University of Puerto Rico. Also during this period I consulted for NSF on the Model Institutions of Excellence award to Oglala Lakota College in South Dakota.

At present I am the IEEE Computer Society (IEEE-CS) liaison to the Executive Board for the Association for Computer and Information Science and Engineering Departments at Minority Institutions (ADMI). Since 1996, I have assisted in organizing ADMI's yearly Symposia on Computing at Minority Institutions. In addition, I am a member of the Coalition to Diversify Computing sponsored by NPACI, ACM, IEEE-CS, CRA, and ADMI.

From time to time I consult for minority serving institutions on academic programs and writing award proposals to national funding agencies.

Since electing to take early retirement from the University of Kentucky, I have been devoting time to projects intended to encourage minority students to continue their education by attending graduate school in computing.
